TRACTION-PLOW.

To all wlwm it mag concern:

Be it known that I, Gnonen Bon'r'rum, a citizen of. the United States, residing at St. Peters, in the county of St. Charles and State of'Missouri, have invented a new and useful Traction-Plow, of which the following is a specification;

This invention relates to a tract-ion plow and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a traction. plow which consists of. a frame .t pdfnfl ihich-ie m'ou'nted an engine. The for- .W ird portion .of the frame is supported upon a'dirigi ble truck which in turn is supported upon traction wheels of different sizes and: which are operatively connected with the en-. gine upon the said frame. The rear portion of the said frame is supported upon a caster wheel which is operatively connected tosald truck to be guided simultaneously with the same.

lower ng 'said beam and means for swinging hub 17 of a beveled gear whcel15 but the A further object ,of the invention is v to.

provide in combination with a structure as gagbove indicated a beam adapted to support a .-gang of plows with means for raising. and

the beam-in order that the pl'ows'mayv be disposed at desired angles to the surface of In the accompanying; 'dra'wing's;-F igure. .1 is-a top plan view of the plow. Fig. 2 .is a'verti'ca longitudinal sectional view of the same cut on the 'line f2-2 of Fig. 1-.-. Fig. 3 is a vertical transverse sectional. view of the same cut on the line 3',3 of Fig. 1. Fig. 4 is a vertical transverse sectional view of the rear portion of the plow frame cut on the line 4-4 of'Fig. 1. Fig. 5 is a detziil view of a portion of the frame of the The plow includes a frame 1 which is provided at its forward [end with an approximately'circular head'portion 2. The portion 2 is provided at its opposite sides with elongated slots 3; An engine 4, (preferably of the explosive compression type is mounted upon the head portion 2 of the frame 1 and is operatively connected with a crank shaft 5 also mounted-upon the said ortion 2 of the frame 1. A friction memer 6 is mounted upon the crank shaft 5 and is adapted to be en agedby friction shoes 7'carried by a mom er '8 which is slidably mounted upon the shaftl5 and which is con- Specification of Letters Patent.

wheel 9" is mounted upon the member 8 or may be formed integral with the same.

Apshaft 10 is journaled for rotation in bearings 11. provided upon the enlarged portion 2 of the frame 1 and a gear wheel 13 is fixed to 'the shaft 10 and meshes with the gear wheel 9. upon the member 8. A sleeve 14' is journaled upon the intermediate portion of the shaft 10 and spaced pinions 15 are journale'd upon the shaft 10 and are located adjacent the ends of the said sleeve [4. The beveled gear wheels 15 are held in position against the ends of the sleeve14 by means of a yoke 16 which is attached at 'a point intermediate its ends to the enlarged portion 2 of the frame 1. The several gear member 18 is locatedfadjacent the clutch clutch members 18 at the opposite sides of the machine are connected together aswillf be explained.

- A bar 19 is slidably mounted infa yoke 20 provided upon the enlarged portion 2 of the frame 1. Arms 21 are attached to the ends of the bar 19 and also connected with the clutch members 18 above described. .A

collar 22 is fixed to the intermediate portion 1 f the bar 19 and one end of a lever 23, is. pivotally connected with said collar 22 and the said lever 23 is fulcrumed upon the enlarged portion 2 of the frame 1. By this arrangement it will be seen that by swinging the lever 23 that the collar 22 and the bar '19 will be moved transversely of the machine and the said bar 19 will carry with it the" and when one is rotated in the manner as indicated, it will be seen that the clutch.

An-axle 24 passestransversely through the slots 3 provided at the opposlte sides of the enlarged head 2 of the frame .1 and traction wheels'25 and 26 are located upon 7 the end portions of the saidaxle. The traction wheel 25 "is-aofgreater diameter'than thetraction wheel 26 and is adapted to- I travel in the furrow, while the said traction wheel-26 isadapted totravel-upon the surfaceof the unbroken ground. The traction wheels 25 and 26. are mounted upon sleeves 27 which in turn are journaled upon the axle 24 above mentioned A frame 28 is 'mounted upon the sleeve 27 and fits Sun ly within the enlarged circular portionthe frame 1. The said frame. 28may turn in the enlarged. portion 2 of the frame 1 and is prevented from having undue fric tional contact with thesame by means of anti-friction .devices 29 and 30 located 1 at appropriate points. along theenlarged por- .tion 20f the frame 1. A yoke 31 is secured at its ends to the frame 28 and forms a component part of the truck frameof whlch 5 the part 28 is also a member. A stub .shaft .32 is journaled for rotation in the inter-l mediate portion of the yoke 31 and isprovidedat its upper end with a beveled gear wheel 33 which meshes with both of the .30 beveled gear wheels '15. Ananti-friction bearing 34is provided. for the shaft 32 and is located above the intermediate portion of the yoke 31. A beveled pinion or gear wheel 35is fixed to the lower? end of the 35 stub shaft 32 and meshes with, a; beveled gear wheel 36 which is fixed to the axle 24 and which forms a component member .of a com ensating gearing of which gear wheels -7 also form component parts. The

140 gear wheels 37 are fixed tothe inner ends of the sleeves 27' while the gear wheel 36 I is mounted upon the axle 24, as indicated.

From the .above description it will be 7 seen that as rotary movement is transmitted ,45 fromthe shaft 10 through one ofthe beveled gear wheels 15 to the shaft32, the said shaft will be; turned in one direction, but when rotary movement is transmitted to the said shaft 32 through the. other beveled gear wheel 15 the said shaft 32 will be rotated in the opposite direction. Thus while the crank shaft 5 may rotate continuously in 1 one direction means 'is provided for transmitting rotary movement from. the said '55 crank shaft 5 in either direction to the shaft v 32and from the shaft 32 through. the transngtting part to the traction wheels 25 and 2 A caster wheel 40 is located at the rear end of the frame 1 and is provided with a frame 41v the shank of which is journaled in the rear portion of the frame 1. upper portion of the shank of the frame of the caster wheel 40 is laterally disposed as illustrated in Fig. 1 of the drawings The and the rear end bra connecting rod 43 is adjustably attached thereto. The forward end of the said connecting rod 43 is pivotally connected with one end portion ofthe .yoke. 31 as illustrated in Fig. 3 of the drawings/ 'Ashaft 44 is journaled for rotation upon the frame 1 and is provided at its forward end with a gear wheel 45 which meshes with a gear rack 46 formed at the upper edge of the rear portion of the frame 28. -A worm wheel 47 is fixed to the rear end of' the shaft 44 and is engaged by aworm '48 fixed to the lower portionof a vertically disposed shaft 49. The shaft 49 is journaled for rotationat the rearportion of the frame 1 and isprovided at its upper end with a hand wheel 50. Thus it will be seen that as theshaft 49 is'rotated through the instrumentality of the wheel 50 the worm 48 engaging the worm wheel 47 will rotate the shaft 44 and through the said shaft and I the intermshing gear wheel45 and-gear rack 46 the frame 28 will be turned within the forward enlarged portion 2 of the frame 1. It is of course understood that as the-' frame 28 rotates within the portion 2 of the frame 1 that-the axle-24 and the parts-- mounted thereon will be swung about a vertical-axis within the enlarged portion 2 of the frame and thus means is provided for steering or directing the traction-wheels 25 and26. At the same time through the instrumentality of the connecting .rod- 43' with the yoke'31 which forms a component part of thesaid truck frame, the frame 41. 1

fof the caster wheel 40 is swung so that they caster wheel 40 is steered simultanev ously withthe steering of the traction wheels 25and 26. .The parts are so connected how-' ever that when the traction wheels 25 and 26- turn in, one direction the 'caster wheel 40 y is simultaneously turnedin the oppositedi fl j also mounted upon the beam 53 andare located in advance of the furrow openers 55 1n the usual manner. Cross bars 57 are located .upon the intermediate port-ion of the frame 1 and are in turnprovided with approximately arcuate intermediate portions.

A frame 58 is slidably mounted upon the cross bars 57 and a lever mechanism 59' is mounted upon the rear portion of theframe 1 and is operatively connected with the said frame '58 and is adapted when operated to slidetheframe 58 along the intermediate arcuate portions of the cross bars 57.

' Pintles 60 are journaled in the frame 58 and are provided at their ends with fixed pinions 61. A lever 62 is fulcrumed upon the frame 58 and is provided at its lower end with an arcuate portion having gear teeth 63 which gear teeth mesh with the pinions 61' upon the pintles 60. Arms 64 are fixed to the pintles 60 and the lower ends of the said arms 64 are pivoted to collars 65 which may be slidably mounted upon the intermediate portion of the beam 53. By this arrangement it will be seen that by swinging the lever 62 through the intermeshing gear teeth 63 and pinions 61, the

'pintles 60 will be rotated upon their'axes (floples of'this patent may be obtained for whereby the arms 64 will be swung and through the connecting collars 65 the beam 53 will be raised and lowered in the slots 52 0f the hangers 51. Thus means is provided for raising and lowerin the furrow openers 55 and colters 56. A so by swinging the lever 59 the frame 58 may be moved along the intermediate arcuate portions of the cross bars 57 and thus through the arms 64 and collars 65 the beam 53 will be turned in the elongated slots 52 provided in the hangers 51 and thus means is provided for sup ortin the furrow openers 55 at a desire angl e'with relation to the surface of the soil.

Having described the invention what I claim as new and desire to secure by Letters Patent is A tractor, having a main frame, a steering caster wheel mounted centrally in the rear end thereof and a sole support therefor, a rotatable axle, a pair of traction wheels connected thereto, said caster wheel being adapted to run within the furrow and having its engaging line below but in parallel with the line of contact of the traction wheels, a yoke mounted at the forward end of the frame, a circular frame secured to the terminals of the yoke, and having the axle passin through the frame and yoke, a vertically isposed stub shaft mounted for rotation in the yoke, co-acting gears carried by the lower ends of the stub shaft andaxle, a circular guiding means carried by the main frame and surrounding the circular frame, a motor carried by the main framei means operably connecting the upper en of the stub shaft and motor, whereby the yoke is permitted an oscillatory movement to steer the machine by the traction wheels and simultaneously transmit motion to the traction wheels, and means for operably connecting the yoke and caster wheel to permit steering co-action between said yoke and said caster wheel.

In testimony that. I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
